I have the same problem with my CD copy of Home and Business, after initial update it would not launch. I searched for this problem and was directed to a link on Turbotax.com to download, except there's no Home and Business version. Where can I file the Home and Business download?
Use the following link to download a version of TurboTax Desktop/Download:
